Be it knownthat I, Rosana B. WEAVER,

' a-citizen of th''Unit d States of America, and J resident of Detroit, in the county of. -'--t\lVayne and State. of Michigan, 'have'invented certain new and useful, Improvements. in Drilling-Machines'fof which the following is a full,clear, and exact descrip- Thisinvention. relates-to a. drilling machineof the class inwhich'are comprised. .niultipledrill. spindles which are adjustable radially relatively tothe feed 1 the drills are-carried." j The object of this invention" is to provide a means whereby the drill spindles have what may be termed universal adjustments on the feed head, that 'is, they maybe individu- -"ally nearer-to or farther from the axis of head inwhich the head as. desired, and they may have I with the accompanying drawings and is set 'forth 1n the claims.

their arrangements around the feed .head eitherin uniform separation or inun'equal separation as may be desired, provision being made for the 'drivingof the spindles, ca- 2 'pableof1the adjustmentsas aforesaid, Without the requirement of shafts, individual to the drill spindles, made telescopic and with universal joint connections.

' The drilling mach'ne constructed under and in accordance with this inventionicomprises a hollow downwardly opening .head' havingf a driving' spindle entered centrally ftherethroii gh and; provided. with a gear wheel and a plurality" of drill spindle supports engaged under, and with, thecircular lower portion of the head and revolubly ad- -justable therearound, saidsupports carrying drill spindles having gear wheelsthere- 'on in mesh with the driving spindle gear dle's'may be operated at any, desired distance from the axis of .thehead.

Similar characters of reference indicate -'corresponding'-parts in allof the views.

I In the drawings, A represents an upright 19 multiple spindle drilling machine'of a, usual type, including the head B which carries the multiple drill spindles C C, mechanism shown in a general way in Fig.4 but not ea-r 'ed higher or lower'thaniother of the 60 4 The mac ine furthermore,comprisesim-1 I Each of the plates G .cluded for imparting the vertical feed and retiring movement to the head B; and in this machine the rotatively driven shaft or, spindle D is the one which, suitably rotatively driven, imparts the rotary move.- ments to all of the drill spindles.

The feed head B is made in the form of an inverted basin with a comparatively wide and suitably thickened or reinforced marginal and outwardly extendiiigflange a.

The lowerextremity of'the driving spindle D ii's enteredcentrally through'the upper part of the hollow head,'the latter being constructed thereat for the provision of efficient bearings; and this s indle D has at or near the lower end thereofa detachably connected spur gear Wheel E.

Thef flangecl or marginal portion of the feed head B is constructed with concentric circular downwardly opening T-grooves Z) 6.

G G represent a set of segmental plates, each having at its upper formedfarc shaped rib d which is in engage-- ment in the inner one ofsaid T-grooves b;

andby this manner of rib and groove engagements between the series of plates G and the head, the plates are constrained when they are to be moved foladjustment in circular lines, or with a degree of revolu-- bility, and will be held, when confined, with the utmost stability and against liability of displacement in radial direction. The entire series of the segmental plates G in their aggregate dimension circularly are insufficient to entirely fill the circular space corresponding to the under surface of the marginal'portion of the .feed head so that these plates may bespacedat uniform intervals or some may be close together while others may be unusually widely separated. has a pair of parallel grooves ff in its under side on lines substantially radially of the head, with which engage upstanding ribs 5/ g of support bars J J by which the drill spindles C C arecarried in suitable holders L. Each support bar has a comparatively lengthy longitudinally extending slot It extending vertically therethrough.

i 'represent bolts, the heads of which are engaged in the T-grooves of the feed head and which are passed through holes therctoi-"in the plates G and through the slots h in the support bars J' and on their .lower threaded ends they receive the nuts j which when tightened securely clamp the plates firmly "to the head and the support bars firmlyto the plates.

The drill spindle holders L are vertically adjustable relatively to the support bars J therefor, provisions to this end being in detail as follows: The inner end portion of the support bar and the front portion of the drill tpindle holder are formed with inte- Z grai, matching, lugs or flanges and m, the 7 other drills used in the machine; and

side an integrally which are threaded in the fiang'ed extremitv 1; of the support bar J ,and on the threaded protruding ends of which the clamping nuts 0 are provided. These bolts as shown in Fig. l penetrate with screw engagement into and part way through the flange of the support bar. y temporarily loosening the nuts ofithedrill spindle holders'L may be vertically adjustedso that the holdei's are susceptible of being individually positioned; in case of the drill becoming shortened through breakage and regrinding,.it may be held with itspoint at the samelevel with the again it is possible, should it be so desired, that one. or more of the drills may be "carried higher or lower than other of the drills.

- The drill spindles C Gjournal supported in the axially vertical bores of the drill spindle holders L, have each 011 its upper, end portion a detachably confined spur gear wheel M in mesh with the driving spindle spur wheel or mastergear. These spur gear wheels or pinions M, detachably secured on the upper 'extremities ofthe' drill spindles which are of su'itablyreduced diameter (the gears being held against relative rotative movement by splines or detachable keys) are clamped by the nuts 9 which are made with yertic'al tubular upwardly opening funnel mouthed extensions 8,-fthe mouth portions having their locations. appropriately close to the top wall of the hollow feed head B in which top" wallare the apertures t in circular arrangement and number corresponding to th'number of drill spindles.

t represent removable caps for closing the apertures t. These provisions just described render'it a quick and convenient matter to lubricate the drill spindles, it being manifest that oil introduced through the apertures, enters the wells therefor formed by the said tubular extensions of the nuts to pass therefrom downwardly through the oil ducts M which extend from the upper ends of the drill spindles suitably far downwardly therein and terminate at the sides of the spindles which are located within their hearing supports.

Inasmuch as in this machine there may be occasion for many interchangings of the gear wheels E and M- Mfor other similar gear wheels, but havingdifferent proportionatediameters, gradedsets of such gear wheels. are provided as appurtenances of this machine. a p

The driving spindle ifl has its'lower extremity of reduced "diameter and screw threaded, above which it has the spline rib r.

- The master gear E being forced up in llt Y j $1 the driving spmdle, to turn the nut w clear spindle, until resisted byfthe thrust bearing therein, be wlthdrawn transversely, leavfor its spmdle D is retained by a collar P which has an'aperture w d ndin from its 2 middle toits edge/andfiidh ha? a straddling :relatiorf to the reduced portion rof the spindle the nut m completing the" c on-,

finementfof-theparts engaged as described; The nut 00 is, in its ma' Ximjum diameter,

smaller. than the, openingthrough the gear. wheel E, while-the collar having the -aperw p U lowerportiomof sald-"head and individually ture isof a diameter greater than the opening through .the gear wheeliand by. thisv means it is not necessary, when a master gear is to be secured on, or dlsconnected from,

'ofi'from the screw threaded portion of the spindle, but to merely loosen it sufficiently to permit thecollar to beunclamped, whereupon the-collar may, because ofthe aperture ingjthe master gear free and unobstructed to be slid downwardly oil from the shaft, it passingfreely over the nut.

.- -'As manifest, thism'achine may utilized fortall theoperations possible to be ,accompiiished by'the heretofore extensively used upright} multiple spindle drilling machine requiring it. the organization thereof that the individual (drill spindles comprise shaft sections arranged at angles to eachother and universally joint connected, and such shaft sections in some instances beingof-teleseopic "character.-

. In this machine, a comparatively large master gear and small drill spindle gears may be em loyed-or vice versa; the circle in which the be one of comparatively long or short 'radiiis, accordingly as a large or small diameteredmaster gearis employed, and the drill Spindles "at whatever distance from the axis I of ,the feed head may be spaced at'uniform separation or at, irregular intervals; andwhen lessthan all of the drill spindles are needed on any given work, one or several of the drill sp'indleswith' their holders or sup; ports may be most conveniently and readily removed from thehead, to be. as easilyreplaced when desirable or necessary. The

drill spindle holders, moreover, are susceptible of convenient vertical adjustments to ,jrectify any inequalities in the lengths of the j difi'erent drills of the set used in the machine, And as manifest, this machine when fitted hp and adjusted for its work is one in which the operating tools will be' always carriedon their desired and given set lines without any tendency or possibility of dis.-

placement. therefrom: and it will also'be apparent that .the parts comprised-in this invention, and above described are of such form and nature as to besubjected to little or no' we'a-r in use, thereby 'conducing greatly. to thework ng life of the machine, Also.
